Abstract
Hydropolitics between China, India, and neighboring South Asian nations, especially concerning shared water resources along the Yarlung Tsangpo River (Brahmaputra in India), is a significant concern. This study examines political, economic, and environmental interactions within the basin across China, India, Bangladesh, and Bhutan. It assesses China’s hydropower projects' impacts on downstream regions, notably in India, emphasizing challenges like water availability, ecological balance, and livelihoods. While China delays its water diversion plans, midstream dam construction poses challenges. The paper advocates cooperative frameworks for effective water resource management, underscoring transboundary water issues' role in regional geopolitics. It explores broader consequences of water insecurity on socio-economic development and environmental sustainability, contributing to understanding Yarlung Tsangpo River hydro-politics amidst growing water scarcity and competition in Asia. This research highlights four major dam projects which cumulatively exceed 1500 MW in capacity and threaten more than 20 million people living downstream. The results have practical implications for developing cooperative models and pre-emptive systems for managing trans-boundary rivers in South Asia.
